  1. Notes: Values are n (%); Prevalence = prevalence of disability at baseline; Incidence = the percentage of older adults with no disability at baseline who reported disability in Wave 2; Mobility disability: Participants who answered ‘difficult’ to walk around the perimeter of a playground (approximately 400 m) or to climb a flight of stairs (10 steps); Each ADL and IADL disability: number and percentage of the participants who answered as ‘partially dependent’ or ‘fully dependent’; P-value: chi-square p-value between incidence of men and women; asome missing data
